Cyanine5 hydrazide is a reactive dye for the labeling of aldehydes and ketones, an analog of Cy5® hydrazide.

This dye reacts smoothly and nearly quantitatively with various carbonyl groups encountered in biomolecules. Examples are proteins subjected to oxidative stress, glycosylated proteins pre-activated by periodate oxidation (including antobodies), and oligonucleotides with aldehyde moieties.

Cyanine5 hydrazide replaces carbonyl-reactive Cy5®, DyLight 649 dyes.

Cy5 hydrazide 是一种用于标记醛和酮的活性染料,是 Cy5® 酰肼的类似物。

这种染料可以与生物分子中遇到的各种羰基进行平稳且几乎定量的反应。 例子是经受氧化应激的蛋白质、通过高碘酸氧化预活化的糖基化蛋白质(包括抗体)和具有醛部分的寡核苷酸。

Cyanine5 酰肼替代羰基反应性 Cy5®、DyLight 649 染料。
